PURPOSE:To prevent the irregular feed amount of the wire and the deviation of a bent point by allowing a first bonding margin to protrude from the end of a wedge before the wire is cut, and bending it at the base of the margin. CONSTITUTION:A wedge 1 is relatively raised while a wire 2 remains continued from a second bonding part 8 to set the length of the wire 2 between the part 8 and the wedge 1 to l. Then, the wedge 1 is again relatively lowered, and the wire is bent at the part beforehand of the length l from the rising base of the wire. Thereafter, the wedge 1 is relatively moved forward in a state that the rearward movement of the wedge 1 to the wire 2 is stopped, and the rising base of the wire 2 is cut. Thus, the irregular feed amount of the wire 2, the deviation of the bending point, and the lateral bending of the first bonding margin do not possibly occur. |
